Abstract: Steam Generator Abstract A steam generator is fired by a fossil fuel burner.  The generator is shown as producing approximately 80% quality steam to be injected into oil wells to promote secondary recovery.  The flame body from the burner is propagated along the longitudinal axis of a horizontally extended cylindrical chamber.  Water and/or steam is passed through tubes mounted on the internal walls of the cylindrical chamber in order that they may absorb radiant heat from the flame body. The heat absorbing tubes are divided into groups, or sets, to establish the rate of water and/or steam flow through the tubes.  The tubes within each group are extended as a plurality of reaches the length of the cylinder and are joined to each other by 180° bends of that part of the tube between reaches.  Each reach of each tube group is arranged on the internal wall of the cylinder to result in uniform exposure of the tube groups to the radiant heat.  Each tube group is connected by a common feed water manifold and the flow into each group from the manifold is positively controlled to maintain uniformity of feed water flow through the tube groups.

Abstract: INVENTOR:    WALTER REIST            INVENTION:   APPARATUS FOR OPENING FOLDED, BOUND OR              STITCHED MULTI-SHEET PRODUCTS, ESPECIALLY PRINTED PRODUCTS                 ABSTRACT OF THE DISCLOSURE              The folded printed product to be opened is moved with its open side leading towards a stationary separation element.  The separation element contains a flat, tongue-like opening element attached to a shaft extending transversely with respect to the direction of movement of the pinted product.          The opening element is rotatable by means of this shaft.  In its starting position the opening element is directed with its pointed end towards the arriving printed product.  By means of this pointed end the opening element penetrates between the sheets of the printed product.  Thereafter the shaft together with the opening element is rotated in a predetermined direction, for instance in the counterclockwise direction, while there is continued the feed movement of the printed product.  Due to such rotation of the opening element the part of the printed product reposing thereon is raised from the other product part, so that the printed product is opened.  During the course of the further movement of the printed product a stationary hold-open element moves between the opened parts of the printed product, to thereby prevent closing of the opened printed pro-duct.  Further printed products can be stuffed into the printed product which is held in its open condition.  As soon as the opened printed product has completely moved past the separation element, the opening element again is turned back into its starting position.

Abstract: ABSTRACT      Disclosed are apparatus for controlling fluid flow including a circumferential plurality of blades mounted between a parallel pair of axially spaced annular ele-ments.  The interstitial passages between the blades may be varied by the relative rotation of one annular element functioning as  a ring actuator with respect to the stationary second annular element.   The orientation of the circumferential blades is adjusted in unison by cam type engagements between one of the annular elements and the blades.   An appropriate axial clamping force is applied to the assembly to frictionally secure the blades between the annular rings and to prevent end leakage of the fluid between the annular rings and the blade faces adjacent to the rings.  Variation in the clamping forces acting on the blades as the blades are pivotally rotated to vary the passage cross sections therebetween may be controlled by providing pressurizable pockets in the blade faces adjacent to one or both of the annular elements.   Such pockets may also be provided in one or both of the annular elements,  alone or  in combination with pockets in the blades.   Fluid pressure is communi-cated to, or vented from, the pockets at various orien-tations of the blades, thus controlling the clamping force magnitude for any given blade orientation.

Abstract: 11                  49,234 ABSTRACT OF THE DISCLOSURE A multiple strand drive chain for transmitting power from toothed sprockets to an endless belt construct-ed of toothed links.  The strand which cooperates with the toothed  links has  a plurality of  spaced rollers,  with alternate rollers, which have a first predetermined dia-meter, being constructed of a deformable, resilient mater-ial.  The intervening rollers, which have a smaller dia-meter  than  the  first predetermined diameter,  are  con-structed of a substantially non-deformable,  rigid mater-ial.  The deformable rollers normally share the driving load in a substantially uniform manner, but as the chain wears  the  sharing  becomes  disproportionate.   The  non-deformable rollers greatly extend chain life by limiting the maximum driving  load placed on  any one deformable roller.

Abstract: Abstract of the Disclosure A process and an apparatus for the determination of the total leakage impedance and the maximum conductor contact current of an ungrounded AC power supply system resulting from the total leakage impedance.  An AC mea-surement current is fed into the AC power supply system, which flows through the system leakage impedances and has a continuous dynamic phase-shift with respect to the power supply frequency so that, between supply system and ground, an interference pattern will be formed between the super-imposed AC measurement voltage and system voltage component at an interference pattern frequency (difference or beat frequency) of the pattern envelopes which is small with respect to the system frequency.  By extracting and pro-cessing of the components of the interference pattern, it is possible to determine the AC measurement voltage component contained in the interference pattern.  This allows a very precise determination of the total leakage impedance corresponding to the system frequency, and also of the maximum conductor contact current corresponding the total leakage impedance, e.g. by employing a frequency difference of no more than 2 Hertz between the measurement frequency and the system frequency.
